If that's the case, YearMonth should be more than enough. This post is from 2026-08. This gives you enough context of what was happening at the time, but with no more context than necessary. I'm suggesting that as a compromise. I really like the absence of likes, timestamps, counters, and so on. Text is timeless. I don't need the precise timestamp of the Complaint Tablet to Ea-Nasir to laugh at Nanni and his messenger being treated with contempt.
